About AI training work

AI training (data labeling, annotation, and human feedback) is the human side of building AI. Contributors prepare and review examples that teach models to interpret data, reason, and answer correctly—work that is remote, often flexible, and on the cutting edge of technology.

• Accessible: many projects need no prior experience beyond language fluency and attention to detail.
• Impactful: your annotations and scenarios directly shape how models reason and respond.

The role

You will join OpenTrain as a German-English LLM Analytical Data Reviewer on a short contract to help fine-tune large language models. This role centers on reviewing, labeling, and creating analytical text scenarios to improve model reasoning, logical deduction, and data interpretation.

• Contract length: 1 week, 40 hours total per week.
• Schedule: flexible hours except for 4 hours daily overlap with UTC-8 (America/Los_Angeles).
• Work type: fully remote; text-only data (classification and evaluation/rating tasks).
• Employment: contractor, part-time/short-term engagement.

What you'll do

• Review, label, classify, and validate analytical text according to project guidelines.
• Answer analytical questions and create training scenarios that teach correct reasoning.
• Identify edge cases, discrepancies, and annotation issues and escalate when needed.
• Ensure accuracy, consistency, and quality while meeting productivity targets.
• Collaborate with the project team through written feedback and quality checks.

Requirements

• Bilingual proficiency in German and English (mandatory).
• Strong analytical, logical reasoning, and research skills.
• Creative and lateral thinking to craft and evaluate scenarios.

• Experience writing professionally (business analyst, research analyst, copywriter, journalist, technical writer, editor, translator, etc.).
• Familiarity with Excel and Google Workspace.
• Comfort with basic arithmetic, data interpretation, and structured logical problems.

How the contract works & compensation

This is a short, focused engagement where quality and productivity targets are tracked. You will complete text labeling and rating tasks remotely and follow provided annotation guidelines. Compensation is competitive and based on experience; specific pay details are provided during onboarding.

• Tasks are delivered and reviewed through OpenTrain workflows; no prior platform experience is required.
